Show 1875.] SPECIES OF SPHINGIDCE. 247 22. PANACRA REGULARIS, n. sp. Intermediate in character between P. metallica and P. vigil; differs from both in the perfectly regular oblique outer margin of primaries: wings above brown; primaries olivaceous, with the disk whitish from inner margin to centre of wing; basicostal area speckled with black, especially towards costa; base of costal area dark brown, remaider of costa pale, rather yellow at the edge; six oblique curved parallel discal dark brown lines, the three innermost filled in with smoky brown, radial nervures and external area between them dark ; apex with a zigzag silvery white oblique litura; three apical submarginal blackish spots upon the nervures: secondaries pale smoky brown, costa whitish, abdominal area pale; anal angle whitish, margin and a submarginal streak dark brown: body almost as in P. automedon, but paler: primaries below dull brown, costa and external third greyish varied with pale buff and freckled with black; a discal series of black points: secondaries brownish grey mottled with dark brown and buff, a discal waved series of blackish points. Expanse of wings 2 inches 4 lines. Java. Type, coll. F. Moore. A very distinct and interesting species. Genus CHCEROCAMPA, Duponchel. 23. CHCEROCAMPA LEWISII, n. sp. Very like C. elpenor, but duller above, the rosy streaks on primaries less evident, primaries below with the golden discal patch not extending (except as a fine line) below lower radial. Expanse of wings 2 inches, 10 lines. Japan (Lewis). Larva very distinct from C. elpenor, brown or green. The brown larva differs principally in having the lower surface and lateral area of the last seven segments brown, with a defined undate-sinuate internal edge, each sinuosity answering to the convex margin of its segment; the two eye-like spots are much smaller and have pale brownish centres in both forms of the larva; the horn in the green form is longer but less curved than in the brown form. It feeds on Fuchsia and Balsam. Without having seen the excellent figures of the trasformations obtained by Mr. Lewis, I should not for a moment have thought this species distinct from C. elpenor. 24. CHCEROCAMPA FRATERNA, n. sp. General aspect of C. macromera, but duller: primaries above golden olivaceous, with the two oblique bands and border dull greyish pink; secondaries with basal half dull black, external half dull pink, fringe whitish; body altogether duller: wings below bright rose-red, costae ochreous, a central grey-brown transverse line; basal half of primaries brown, clothed to first median branch with ochreous and pink hairs : body below rose-red, abdomen with lateral white dots. Expanse of wings 3 inches 2 lines. Simla (coll. F. Moore) ; N. India. B.M. |
